The Walking Dead Season 4 Features Mysterious New Threat: New Bad Ass Carl Image

The latest issue of Entertainment Weekly features three different character covers for The Walking Dead Season 4 where it's stated that not only will the zombies take center stage, but that a mysterious "menace" threatens Rick's group from within the prison.

“The new threat is something you can’t just stab in the face,” new showrunner Scott M. Gimple said. “You can’t talk sense to it. You can’t make a truce with it. It’s beyond all that. It would be a threat in any world, but in this world it is much more terrifying.”
